#9121: Presence of dyn_o files not checked upon recompilation -------------------------------------+------------------------------------- Reporter: andreas.abel | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Driver | Version: 7.8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ppetr): I can confirm this happens for other packages as well. I was compiling arithmoi==0.4.1.3 against stackage-lts-3.17 with GHC 7.10.2 and cabal 1.22.6.0 (cabal library 1.22.4.0). I interrupted cabal during the build phase, and when compiling again, it failed with {{{ gcc: error: dist/build/Math/NumberTheory/GCD.dyn_o: No such file or directory }}} Recompiling diidn't help {{{ $ cabal build -j Warning: /home/p/.cabal/config: Unrecognized field constraints on line 5 Building arithmoi-0.4.1.3... Preprocessing library arithmoi-0.4.1.3... gcc: error: dist/build/Math/NumberTheory/GCD.dyn_o: No such file or directory }}} but ''cabal clean'' and rebuilding everything solved the problem. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9121#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
